These are all Bachmann Spectrum engines, according to their site they are simply based on locomotives from the Baldwin company.
First up the beauty and scale shots:
2-6-0 Mogul, lettered and some what modified for the Colorado & Southern. Not sure how close this one is to an actual C&S 2-6-0. |
The 4-4-0 American, unlettered, will definitely need to be painted. |
The 4-6-0 Ten Wheeler, another one with a date with the paint shop |
This probably gives you the best look at the difference in sizes |
Another good comparison shot |
